WEB-PUNCHING MECHANISIMI.

Applioationiled February 19, 1923. Serial No. 620,116..

To all fwkomiz't may concern Be it known that I, GEORGE W. SWIFT, J r.,a citizen of the United States, and resident or Bordentown, county ofBurlington, and

5 State of New Jersey, have invented certain new and useful Improvementsin Web- Punching Mechanisms, of which the following is a specification.i

. The present invention relates to an improved mechanism forv punchingor other- Wise marking a succession of printed forms upon'a travelingweb. The improved mechanism may be used for producing anyl desiredsuccessiveimpressions u on a web or series of sheets, but is particuarly applicable for punching holes at the desired intervals in atraveling web.

The improved punching or marking mechanism comprises a pair ofoscillatory shafts mounted in parallel relation and having means actingthrough one shaft for imparting a to and fro oscillating motion andmeans acting through the other shaft for causing intermittent bodilymovemnt of one shaft toward and away from the other. The relativelymovable oscillatory shafts carry `either one or both printing, punchingor other marking devices for acting upon a web or sheets that passbetween the shafts. The devices-for oscillating the shaft and for bodilymoving one shaft toward and away from the other are preferably actuatedfrom the common drive, which is operated at a proportional speed withrelation to the feed of the web -or sheets. This proportional Speed willdiffer for different ,form lengths which are operated upon and for theready adjustment of the speed of operation of the punching or numberingshafts with relation to the feed of the web I provide a changeableproportional gear mechanism of any suitable form.v The shaft oscillatingdevices are adjustable independently of their driving mechanism toaccurately adjust the speed of oscillation to the surface speed of theweb or sheets, without regard to the adjusted periodic bodily movementof the shaft.

More specifically the 'preferred embodiment of the improved machineincludes an f oscillatory shaft mounted in fixed bearings, a companionshaft mounted in adjustable and the main drive shaft of the machine lfrom which the web or sheeets are driven..

In order that the invention may be fully understood it will first bedescribed with reference to the accompanying drawings and afterwardspointed out more particularly in the annexed claims.

In said drawings: y M

Fig. 1 is a detail lan view of a section of a web machine to w ich theimproved mechanism in the form of a multiple web punch is applied, thisview being taken in the direction of the arrow 1 of Fig. 2.

Fig. 2 is a detail side elevation of the same mechanism.

Figs. 3 and 4 are detail sectional views taken on the lines 3 3 and 4 4of Fig. 2.

Figs. 5, 6 and 7 are detail sectional views taken respectively on thelines 5 5, 6 6 and 7 7 of Fig. 1.

Figs. 8, 9, 10 and 11 are diagrammatic views illustrating the operationof the improved punching mechanism.

The improved mechanism is shown as part of almachine arranged to print,punch and number forms or bills upon a traveling web or successionof'sheets of paper. The embodiment of the present invention is a webpunching mechanism arranged to punch the desired holes in the properlocation in the printed forms of a traveling web.

1 and 2 are the side frames of the machine. 10 is a transverse shaftjournalled in fixed bearings in the side frames 1, 2 and carryingbetween its ends a number of adjustably mounted punch members 11. 15 isThe eccentric bushings 16 `are journalled in suitable bearings in theside frames 1 and 2 so that in their rotation they will cause the shaftV15 to move bodily toward and away from the shaft 10. l

indicates a webor series of sheets of paper passing between guide rolls21 and up between the shafts `10 and 15 in the plane in which the punchand die members operateb for punching openings in the passing we Shaft10 has adjustably secured to its projecting end a crank arm 25 mountedupon a Split collar 26 by which itis attached to shaft 10. A pitman 28connects crank pin 25 with a crank pin 30 formed upon a disk 31 adjustably mounted in an eccentric recess 32 by means of set screws 33. Adisk 35 is mounted upon the projecting end of a shaft freely journalledin the side frame 1 and carrying at its opposite end a beveled gear 41meshing with and driven by a similar gear 42, which is adjustablvsecured to a driving shaft 50 by means of a splined hub 43 and setscrews 44. By loosening the screws 44 the gear 42 can be adjusted aroundshaft 50 and afterwards securely fastened in the desired adjustedposition.

gear 65 is in constant mesh with a similar ring gear 70 adjustablymounted upon a flanged bearing bushing 75 by means of flanged set screws71. The bushin 75 is freely journalled in one of the side rames and issplined or keyed as indicated at 76 to the end of a transverse shaft 80carryinor at one end a beveled gear 85 meshing with a similar gear 86adjustably mounted upon shaft 50 by means of a splined collar 87 and setscrews The specific description of geared busliings 16 and 76 is withreference to one end only of the shafts 15 and 80, but it should beunderstood that thesame arrangement of geared bushings is also providedat the opposite end of these shafts so that the rotation of bushings 16at opposite ends of shaft 15 will cause an even bodily movement of shaft15 toward and away from shaft 10.

The common drive shaft 50 is suitably journalled in horizontal positionupon the side frame 2 by means of bearing brackets 90. This shaft 50must be driven by suitable gearing from the main drive shaft ot' themachine. The speed of shaft 50 must have a proper proportional relationto the surface speed of the web to be operated circumferentiall upon.This proportional speed will dier with different length forms that havebeen printed upon the web, since the periodic bodily movement of shaft15 toward shaft.

10 determines the number of punching operations upon the web. In Fig. 1is shown more or less diagrammatically a gear 95 upon shaft 50 driventhrough intermediate gear 96 upon a stud shaft that is adjustable ofgear 95 and a ear 97 upon the mainl riving shaft 100. T e gear 95 ismade removable and chan eable so that by mounting the proper size o gear97 upon shaft 100 the desired speed ratio between the punching operationand traveling web can be obtained.

In the operation of punching a web, it will be understood that therotation of eccentric bushing 16 moves shaft 15 carrying the die memberstoward and away from shaft 10 carrying the punch members. As the punchand die members come into cooperative relation the shafts 10 and 11 arerocked by the crank and pitman device described to cause the punch anddie members to travel in the same direction and at the same speed as theweb 20 which is fastened between them. At the completion of each punchinoperation the bushings 16 separate the sha t sufficiently to disengagethe punch and die membeis for their return stroke.

It will be understood that the adjustments shown enable the operator tofirst determine the necessary periodic operation of the punches to suitthe length of forms to be operated upon. This is accomplished bymounting the proper size of driving gear 97 upon the shaft 100. It thenbecomes necessary to adjust the cranks 25 and 30 to get the proper throwand speed of the crank when the punch and die members are brought intocooperative relation. These parts can be adjusted to nicety to cause thepunch and die members to o erate at the exact speed of the travelin weupon which they operate. Figs. 9 an 11 show plan views of two webs withdifferent form lengths indicated upon them, the forms of Fig. 9 beingtwice the length of those in Fig. 11. It will be understood that topunch the short form length of Fig. 11, it is necessary that themechanism be adjusted to operate twice as fast as for those form lengthsshown in Fig. 9, that is the number of bodily movements of shaft 15toward shaft 10 in unching Fig. 11 form lengths must be double thatrequired in punching Fig. 9 form lengths. This is true on the assumptionthat the speed of the web operated upon is the same in both cases. Figs.8 and 10 show respectively the adjustment for these two form lengthsillustrated in Figs. 9 and 11. It will be noted in Fig. 8 that the throwof the crank for oscillating the shafts 10 and 15 is greater and fasterwhen operating upon shafts 10 and 15 is, however, the same in bothcases.
